Another 45 percent remain uncommitted to their top choice, meaning that any of the top candidates could see significant gains or drops in their support levels before next week's caucuses.

No other candidates registered above 6 percent support in the poll, suggesting a clear divide between the top four candidates and the remainder of the Democratic field in the first-in-the-nation caucus state.

USA Today/Suffolk University's poll surveyed 500 likely caucusgoers by landline and cell phones between Jan. 23-26. The margin of error is 4.4 percentage points.
